[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine inspection apparatus and a game machine inspection method for inspecting a ball-and-ball game machine such as a pachinko machine, a spinning-type game machine, and other various game machines.

[0002]

2. Description of the Related Art In the process of assembling a ball-and-ball game machine such as a pachinko machine, a game board unit is assembled by mounting game parts such as a ball entrance, a winning means, a display lamp, and a variable symbol display means on a game board. Later, the game board unit is sent to the inspection line,
In the inspection line, the inspector sequentially puts game balls into the entrance, prize means, etc., and inspects whether or not each game part operates normally, and uses each terminal such as display lamps, fluctuating symbol display means, etc. A method of applying an inspection signal and inspecting for the presence or absence of a disconnection is employed.

After the game board unit is transported to the inspection device side of the inspection line, the inspection head of the inspection device is moved to the game board unit side, and the contact pins are connected to the connector of the relay board of the game board unit. Connect, and apply an inspection signal from the inspection head to the electric components on the gaming board unit side to automatically inspect the disconnection or short-circuit, etc. An automatic inspection method and the like that are arranged to be divided into two types have been considered.

In addition, a compulsory ROM or the like in which an inspection program is built is provided on the inspection apparatus side, and an inspection signal is inputted from the compulsory ROM or the like to a variation symbol display means of the game board, and a big hit symbol is displayed on the variation symbol display means. In some cases, a reach symbol, an off symbol, or the like is displayed to check for an abnormality.

SUMMARY OF THE INVENTION In the conventional inspection method,
The quality of the game board unit can be inspected, and particularly when an automatic inspection method is adopted, the inspection can be performed automatically, so that there is an advantage that labor and efficiency of the inspection work can be reduced. However, in the conventional automatic inspection method, a game ball is inserted into a ball entrance or the like, or an inspection signal is applied to a display lamp or the like to perform an inspection.
In the case of a pachinko machine or the like that employs variable symbol display means,
There is a problem that the inspection time becomes very long and the inspection cannot be performed quickly and efficiently.

That is, in the case of a pachinko machine or the like which employs a variable symbol display means, a random number generating means including a pulse generating means and a counting means, a random number determining means, a variable processing means are provided on a control board on the rear side of the game board. The ROM and other electronic components that make up the same stage are mounted, and when the game ball wins at the starting port, the display symbol of the variable symbol display means is fixed by random number processing by the random number determination means on the control board side, the variable processing means, etc. When the stop symbol after the change becomes a predetermined jackpot symbol, or when the game ball passes through the operation area thereafter, a predetermined right is generated, and after the right is generated, the special winning means is repeated a plurality of times. A great profit is returned to the player by a method such as opening and closing.

For this reason, the probability of occurrence of a jackpot is 1/280.
In the pachinko machine set before and after, when inspecting the good or bad of the operation state of each gaming component at the time of occurrence of a big hit by the conventional inspection method, sequentially to the starting means until the stop symbol of the variable symbol display means becomes a big hit symbol. The game balls must be kept inserted, which requires an extremely long inspection time. Therefore, with the conventional inspection method, if all pachinko machines are inspected, a huge amount of inspection time is required, and the entire assembly line is stopped in the inspection process, which is practically impossible. It is necessary to adopt a sampling inspection method in which a pachinko machine is extracted and inspected.

In the inspection method using an inspection device having a forced ROM or the like, an inspection signal is input to the variable symbol display means for inspection. Therefore, the presence or absence of an abnormality in the variable symbol display means itself can be easily determined. In a game, it cannot be inspected under the same situation as when a game ball enters the starting means. For this reason, in the related art, there is no other method than relying on the inspection result at the manufacturing stage of the control board, and the control system including the entire control system such as the random number generation means and the random number determination means on the control board side is not included. There was a problem that it was not possible to check for abnormalities. The present invention has been made in view of such a conventional problem, and has provided a gaming machine inspection apparatus capable of inspecting an entirety including a variable symbol display means and a control system thereof as an inspection object, and performing the inspection easily, efficiently, and quickly in a short time. An object of the present invention is to provide a gaming machine inspection method.

And second calculating means 51 for counting the number of clock pulses of the pulse generating means 41 by the difference between the two calculated by the first calculating means 50 and calculating the generation time of the inspection signal. Alternatively, the inspection signal is output to the control board 31 of the pachinko machine 1 instead of the start signal of the start means 23 in accordance with any of the random numbers.

The start control means 45 includes a socket for the power plug 55 on the pachinko machine 1 side, a push button switch, and the like. When the push button switch is operated after inserting the power plug 55 on the pachinko machine 1 side into the socket, Pachinko machine 1
Is turned on and the pulse generating means 4 on the control board 31 side is turned on.
1, at the same time that the counting means 33 for random number generation starts operation,
The pulse generating means 41 and the inspection counting means 42 start operating.

In this embodiment, the pachinko machine 1 generates an inspection signal with a 1/3 probability of occurrence in accordance with the timing of each of the jackpot random number, the reach random number and the outlier random number. The test signal may be generated in accordance with the generation time of a control random number with a low probability of occurrence, for example, a jackpot random number, among the generated random numbers on the one side.

Next, the pachinko machine 1 using the inspection device 39
The inspection method will be described. In this pachinko machine 1,
Normally, when power is supplied to the power supply unit, the pulse generation means 41 generates a clock pulse, and at the same time, the random number generation counting means 33 starts a counting operation for counting the clock pulse, and the operation is repeated and continued.

Then, when a game ball wins the starting means 23, the start processing signal from the starting means 23 causes the variation processing means to win.
36 changes the display symbol of each symbol display portion 30 of the variable symbol display means 29 for a predetermined time, and the random number generation counting means 33 outputs the count value at the time of input of the start signal to the random number determination means 34 as a control random number, The random number determining means 34 determines whether the random number is a jackpot random number, a reach random number, or an out-of-range random number.

If the result of the determination by the random number determination means 34 is a jackpot random number, the fluctuation processing means 36
The stored information of the 35 big hit symbols is read out, and the stopped symbol after the change of the variable symbol display means 29 is controlled so as to be a big hit symbol such as "7 / 7.7". Is controlled so that the stop symbol of "7" becomes a reach symbol such as "7, 7, 6".

If the result of the judgment by the random number judging means 34 is a jackpot random number, the special winning control means 37 operates and the special winning means 25 is opened after the symbol of the variable symbol display means 29 is stopped, and the large winning prize means 25 is opened. The game balls falling from the upper side can easily win the big winning means 25. Then, when 10 game balls win a prize in the big prize winning means 25 or when a predetermined time elapses after opening,
Under the control of the special winning control means 37, the special winning means 25 is closed.
If a game ball which has won a prize while opening the special winning means 25 passes through the central special operation area 32a, the special winning means 25 is opened again after closing, and the opening and closing operation is repeated up to 16 times.

When a game ball wins in the special winning means 25, the ball payout means 16 pays out the game ball in the prize ball tank 14 to the upper plate 7 at a ratio of 15 to one winning ball, and The profit according to the winning number is returned to the player. When inspecting after assembling this kind of pachinko machine 1, the connector 47 of the starting means 23 of the pachinko machine 1 is connected to the control box.
Fix to 20 side. The pachinko machine to be inspected in this state
When 1 is transported to the inspection position on the inspection line, the inspection head 52 moves to the game board 5 side and connects the contact pins 46 and 48 to the connectors 47 and 49.

When the connection between the inspection device 39 and the pachinko machine 1 is completed, when the start command is issued by operating the push button switch of the start control means 45, the power is turned on to the pachinko machine 1 and the pulse generation means 32, At the same time when the counting means 33 for random number generation starts operating, the pulse generation means 41 and the counting means for inspection 42
Starts operating.

That is, when power is supplied to the pachinko machine 1, the pulse generating means 32 and the counting means 33 for random number generation start to operate, and the counting means 33 for random number generation repeatedly counts the clock pulses generated by the pulse generating means 32. I do. On the other hand, on the inspection device 39 side, similar to the pachinko machine 1 side, the pulse generation means 41
Generates a clock pulse, and starts a counting operation in which the inspection counting means 42 counts the clock pulse. Therefore,
On the pachinko machine 1 side and the inspection device 39 side, pulse generation means 41
Generates clock pulses at exactly the same timing, and the clock pulses are repeatedly counted in a state where the respective counting means 33 and 42 are completely synchronized.

Next, in this state, when a game ball is put into the starting means 23 by manual operation of the inspector or automatic operation of the inspection device 39, when the starting means 23 detects a game ball, a command signal is sent to the inspection counting means 42. The inspection counting means 42 outputs the count value at that time to the first calculation means 50 side. The first calculation means 50 compares the count value of the inspection counting means 42 with the jackpot random number, the reach random number or the out-of-range random number and calculates the deviation value. For example, if the count value of the inspection counting means 42 is 241, the deviation value is calculated by comparing with the subsequent big hit random number of 7. The deviation value in this case is 280 + 7−241 = 4
It becomes 6.

When the first calculating means 50 calculates the deviation value 46, the second calculating means 51 starts counting the clock pulses of the pulse generating means 41 from the time when the command signal is input. When the count of the clock pulse is calculated and confirmed, the inspection signal is input to the pachinko machine 1 instead of the start signal of the start means 23.

In other words, the inspection signal output means 44 determines when the inspection counting means 42 has once counted 280 clock pulses and then counted from 1 to 7, and has counted the seventh clock pulse, that is, the pachinko machine. Machine 1 counting means for random number generation
An inspection signal is input from the contact pin 48 and the starting connector 49 to the control board 31 side at the time when 33 counts the jackpot random number 7.

For this reason, the variation processing means 36 operates to change the display symbol of each symbol display section 30 of the variation symbol display means 29 for a certain period of time, and the random number generation counting means 33 outputs the count value 7, so that the random number is output. The determination means 34 determines the count value 7 as a jackpot random number. Then, after the fluctuation symbol display means 29 continues the fluctuation operation for a certain period of time, the symbol of the fluctuation symbol display means 29 stops at, for example, "7 / 7.7" of the jackpot symbol, and the special winning control means
The operation is the same as when a jackpot occurs during a normal game, such as opening of the special winning means 25 due to 37.

For example, if a game ball is put into the special operation area 32a while the special winning means 25 is being opened, the special winning means 25 is closed and then opened again. In addition, with the occurrence of the jackpot, the display lamps mounted on each part of the game board 5 blink, and sound effects are generated from the speakers. Therefore, the inspector can check the status of the pachinko machine 1 including the game board 5, for example, the changing symbol display means 29.
Of the pachinko machine 1 including the control board 31 by visually checking the fluctuation status of the display, the opening / closing status of the special winning means 25 after stopping at the big hit symbol, the blinking status of each display lamp of the game board 5, etc. Can be easily and efficiently determined and inspected.

In particular, despite the fact that the jackpot occurrence probability is 1/280, the jackpot is generated on the side of the pachinko machine 1 with a probability of 1/3, so that the inspection is easy and efficient, and the pachinko machine after assembly is easy. 1 can be inspected including the control board 31 side, so that the reliability of the product is improved and the shipment of defective products can be prevented as much as possible.

Further, the pulse generating means 32 of the pachinko machine 1 side,
The same pulse generating means 41 as the random number generating counting means 33 and the inspection counting means 42 are provided on the inspection device 39 side, and these are simultaneously operated to perform inspection in accordance with the timing of generating the jackpot random number and the reach random number on the pachinko machine 1 side. Because the signal is output, the signal from the pachinko machine 1 side is
The pachinko machine 1 can easily hit the jackpot and generate a reach without reading and processing on the side.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment. For example, in the embodiment, the pachinko machine 1 is adjusted in accordance with the jackpot random number, the reach random number, and the outlier random number set by the setting unit 43.
Since the inspection signal is input to the side, it is possible to inspect each of the time of occurrence of a jackpot, the occurrence of a reach, and the time of disconnection. However, the inspection may be performed only at the time of occurrence of a jackpot.

In the embodiment, the signal from the starting means 23 is input to the inspection device 39, and the inspection counting means 42 outputs the count value when this signal is input. A command signal may be input by a switch operation, or the command signal may be automatically input after the start of the inspection. Contact pin 46 and contact pin 48 of the embodiment, connector
The 47 and the connector 49 may be configured integrally.

When confirming whether or not there is an abnormality on the pachinko machine 1 side, it may be visually confirmed by the inspector or the inspection device 39.
On the side, liquid crystal display means 22, variable symbol display means 29, big prize winning means
Each inspection item such as 25 may be set, and the presence or absence of an abnormality may be automatically confirmed in sequence according to the inspection item, and the confirmation data may be input to a computer or the like for each pachinko machine 1.

In addition, the inspection device 39 is provided with an inspection function for other display lamps, winning means, switches, and the like.
At the same time, the inspection of the display lamp, the winning means and the like may be performed in parallel. In addition to the pachinko machine 1, it can be implemented not only with ball game machines such as arrange ball machines, but also with other spinning-type game machines, etc., and the game content of each game machine is a special problem. is not.
